Be it-known: that I, ALBERT LJ-STA'DERF MANN, citizen {of th UnitedStates of Anferica' a resident of Terre' Haute county oFYigo'and State'of Indiana, have 'inventeda new and'iiseful Improvement in aDistributing Insulator-Bracket, of which the followingarspecificationl'My invention pertains to the mounting s; particularly wheresuchi'nsul'ator's are mounted in groups, as upon poles bearingfcableterminals. I My. object, is to'provide simpleand safe 'means formounting a pll'urality a plurality of conductors maybeattached fordistribution.

I A' specific instance lies in the distribution 0 f c 11' cuits tosubscribers. premises from atelehone pole, and I have chosen thisinstance. or illustration.

This description is sheets of drawings in which Figure 1 shows elevationof the device of ductors. Fig. 2 shows side elevation of the device ofFig.'1',' Fig: 3'showsside elevation of a modification of the device ofFig. 1, the structural elements being substantially consisting of butthree pairs of 11171511 ators,

Part 1 isio-fi-fiat bar iron, bent into U-shae and pierced in four places 2, 2, 3, 3 'l 1e art 1 to the ole bypassing through the ho es 3, 3. Insu ators 5 may be-of any preferredtype, the sole requirements being an axial perforation, such as is usualin porcelain knobs, and l grooves for tying the conductors, or othermeansfor attaching conductors .to the insulators. A long bolt 6 withnuts 6 is {for the assembling'of the device of Fig. 2) passed at firstthrough insulators for a pair of; com 2, then through a sufficientnumber of insulators to of independfor'the application ofaccompaniedtwo.

It is believed that the nature, the construction and one plan ofinstallation and use of the device of my invention has been fully setforth. I shall ,n'ow pass to modifications.

In Fig. 3' is shown a'modification in 21580 111 blyof the parts used inthe structure of Figs. 1, 2 and 4E. The sole difference lies in the useof a shorterbolt 6, and consequently of fewer insulators upon the bolt.It will be seen that a'bolt of any length within reason may 'be used;also that "a yoke 1 of any length igs. 1 and 2 equipped for. five pairsof conductors.

In Fi 7 is-shown an alternative method of installing the device of myinventi 'n upon atel'ephone ,pole. 10 is end view of a cross arm. Theyoke {1 is perforated in its central ortion to receive two boltswith a.clearance between the bolts of 3% inches, that being the 5 usualthickness of a.telepl10ne cross arm' 12 a bar similarly perforated, and13, 13 are bolts cooperating with the yoke and bar to mount the yoke 1and its insulators by: emlnacing'and clamping the cross arm 10. Thismethod of mounting the device ofmy invention is desirable whendistributing from arms of' 'the' part 1 the bolt 6 is their passedjfdesired, then is'i'sc rewed in place,

- In Fig.5 I show a modified bracket, consisting of a iece of bar 100 at15, t e free ends being bent outwardly an perforated sustain the boltsuch brackets, the rod 17 passing through theinsulators and through theopenings 15 in the brackets-14, 14.
